Малый Актуру, Mountain glacier in Altai Mountains, Russia.

Maly Akturu is a glacier about 3 km long and 3 km² in area in the Kosh-Agach District of the Altai Republic. It fills a valley between the Karatash and Kupol Tryokh Ozer peaks, descending steeply into a gorge. Its upper part, around 3,200 m, is relatively gentle with ice up to 92 m thick; lower down it forms a large icefall before flattening near the terminus at 2,235 m.

Scientists from Tomsk State University began studying the ice mass of this glacier in the early 20th century. Systematic monitoring expanded during the International Geophysical Year and has continued since then.

The glacier's steep tongue hosts ice-training sessions for novice mountaineers and qualification camps for experienced ones. The Aktru alpine camp stands in the taiga on a 19th-century medial moraine, 1.5 km from the terminus, while the Tomsk State University station and an MChS rescue base lie a kilometre further down the valley.

The Tomsk State University research station and a Russian Emergencies Ministry rescue base stand in the larch taiga about a kilometre below the glacier tongue, while the Aktru alpine camp sits on a 19th-century medial moraine 1.5 km from the ice. The tongue drops to 2235 m and its steep lower slope is used for ice training, so crampons and ropes are needed. Temporary ice grottoes can form at the lower edge.

Three permanent markers at the glacier's terminus document the ice retreat and are named after professors from Tomsk State University. These markers visually record how the ice has pulled back over the decades.
